ATTORNEY 1.2 326 r e ntanc filed Apr-ni 'rtesammviwesternerse"MECHANISM;

To all whom mq iwacemzi Be it known that FITHS, a citizen of the UnitedStates, and a resident oi? Philadelphia, in the county of Philadelphiaand State of Pennsylvania, have invented certain new anduset'ulImprovements in Flush-Tank-Valve-Actuating Mechanism, of which thefollowing is a specification.

My invention has for its object to simplify the construction ofmechanism for operating the valve of a flush tank for controlling theflushing action of the latter and it consists in the combination andarrangement of parts as hereinafter more fully described andparticularly set forth in the claim.

In the accompanying drawing 1 have illustrated one form of a convenientembodiment of my invention but it will be understood that changes in thedetails of construction within the scope of the claim may be madewithout departing from my invention.

In the drawings:-Figure 'l is a view partly in front elevation andpartly in section; and Fig. 2 's a view showing a part of the flush tankin-transverse section and certain of the operating mechanism inelevation.

Referring to the drawings, 1 designates a water closet bowl support/edupon a tioor or other support '2 and 3 designates a soil pipe.

4: designates a pipe for supplying water to the flush tank 6 designatesa flush pipe for conveying water from the tank 5 to the upper part ofthe bowl 1 for flushing and cleansing the same. The upper end of thepipe 6 coinmunicates with the lower end of one of the legs of a siphon7. The longer leg oi? the siphon is provided with a port 8 closed by avalve 9 pivoted at 10v For the purpose of opening the valve 9 l haveprovided a rod or bar 12 which extends across the flush tank 5 in theinannerquite clearly shown in Fig. 2 of the drawings which rod ispivotally mounted in hearings on the walls of said tank as shown at 13and 14. The rod is provided with an offset or crank portion 15 to whichthe upper end of a link connection 16 is connected, the lower endthereof being connected at 1'? to the valve 9. One end of the operatingrod or bar 12 extends beyond the side of the ilush Gnirrrrns, orriainnnnnrnia,"rnNnsYLvAnis" Specification ofgietters flatent."

androtated in either direction. In the normal position of the parts thehandle 20 preferably projects downwardly in the manner shown in fulllines in Fig. 1 while the crank portion 15 of the said rod extends in adirection toward the point of connection of.

the link 16 with the valve 9 at 17 so that the said crank and linkconnection 16 are in substantial alinement as is shown in the full anddotted lines in Fig. 1 of the drawings.

\Vhen the handle 20 is turned in either ditank i'isprovidedwvith ahandle 20 by means of which the rod .12 n ayc ber turned 9 and link 16being also shown in dotted lines. The valve may be turned toward theright if desired and in either case may be to make a completerevolution, the rod or bar and its crank also making a completerevolution. It is not necessary, however, that the handle and rod or barbe turned completely around.

l Vhen the valve is opened the water rushes through the port or opening8 and starts siphonic action so that when the valve 9 closes the watercontinues to flow through the siphon and through the flush pipeifi tothe bowl 1 in known manner. As the water; in the tank 5 emptiestherefrom the ball float 2i iiloves downwardly with the water to per: 22to perrhit water to How from theusupply pipe 4 into the tank 5.

When the water has been discharged through the siphon 7 from the'tank 5the siphonic action is broken so that the tank iimnediately begins tofill by reason of the water flowing thereinto from the discharge opening23 from the supply pipe 4. It continues to fill until the float ball 21has been raised to a height sui'liciontto cause the cam 24'. upon theinner end of the lever 25 supporting the said ball to act ripen thevalve 22 to close the same and thus prevent further flow of the waterfrom the pipe i into the tank 5.

it will be seen that applicant has provided a very simple construction.of means for operating the valve 9 and that such nornmiiy 'rneanscontains very few parts with the result that there little likelihood ofthe mechanism. a/ing ou; of order and needing ttepnilz oiaiin:---

The eombii xion of flush wnk valve, a rmatabie n .7 having in arm,a-link haw Ling eonnec on h the said Valve and with the said arm, Hiesaid link and 41m being in substantial aiinement, and

means for rotating said member in eithei' direction for opening the saidvalve.

In testimony that I. claim the foregoin as my invention, i have hereuntosigned name this fourth day of April, A. D. 19141.
